Just took the camshaft position sensor out and the sensor and plug was covered in oil.. Just curious if this has any reason why it would be this way?. Is it suppose to be? I took a pic and put it in my album.. The thread isn't letting me post it. They sent me the wrong sensor so have to call them tomorrow and get the right one on the way. To me the truck seems like the entire timing is off!. Has no power and bogged down like crazy.. I could care less right now bout the blowby it just won't do 10mph..

This should be your priority, if you continue to run it this way you will cause more damage to the most expensive thing under the hood, THE ENGINE!

I would concentrate on one problem at a time since the different codes may be popping up due to one problem that snowballs into creating other codes. I would pull the valve covers first and check the springs and pushrods to make sure that nothing is damaged. Next I would run the compression test on all cylinders making sure that you disable the ignition and crank with the throttle open long enough that the gauge stops registering compression. If these are good then you can feel safe about further testing. Don't feel defeated or screwed just because it is a new truck - sometimes it is just something simple. If you can check these things than you can post back up and there are a lot of folks here that can help.

I'm going to go back to this again. I think if you are seeing that much oil and pressure from the valve cover then you have a mechanical issue and not a faulty sensor. A compression test or a leak down test will confirm this.
 
Cam sensor needs replaced. The incorrect timing and firing is likely causing the blowby. That cam sensor is no good!
 
if you have the sensor out you should be able to ohm the sensor with a meter and know it condition, somebody will have to tell you what number to see to know if its good or bad.
 
Been through this with more trucks than I can remember, including my own.
A bad valve guide, broken ring, piston etc will still let the engine rev. Even with 8 cylinders running our trucks are very responsive. No power equals lack of spark, fuel, or incorrect timing of combustion. With cam/crank sensor being bad PCM starts sparatically firing injectors and coils and is confused. Therefore you'll get no power and combustions happening on wrong stroke forcing air backwards into intake causing your blowby and funny sound through throttle body and filter housing. Like an old 4 barrel sound "thwomp" minus the power. These sensors are getting increasingly hard to find yet being over 10 years old, gen3 engines are going out left and right due to this cam sensor. I do not believe your engine is hurt.
 
I think the real problem is it's a red truck. We know they are all slow and under-powered......except for Trainman's! :D:D
 
How exactly would a cam sensor cause low compression?

He likely didn't good a good reading. Even a low compression reading on all 10 would still run 100 mph and smoothly unless due to a broken piston or rod obviously. He's never stated engine noises whatsoever correct? When an engine is out of time it will absolutely not wanna run 10mph or hardly at all. We're not taking timing being advanced or retarded, rather sporadic blasts of ignition/injectors at the incorrect stroke of the engine. Take a
look at connector on sensor he pictured:burnout:
 
The force is strong with this thread. I predict a lengthy but inexpensive fix on this one. :top:
 
I'm finding it hard to believe that a double roller chain has slipped a cog and put the motor out or timing versus a valve train problem. Either way a valid compression test will get you to the point that you can move past a mechanical issue or dig deeper into this being a mechanical issue.
 
Did you check the flux capacitor modulation sensor? If not, I would start there. No sense in wasting anymore time until you do. This could easily be causing all of the symptoms you have described, including the low compression, excess oil in the breather etc.
 
You need to change that cam sensor. Good luck finding one! If all cylinders have the same compression then it could be a bad guage but still a sound engine. It would still have acceleration. The stumbling felt is due to miss firing. Hookup the O2's properly and clean that cam sensor so it has a good connection. Then try it again. Record the engine codes after that.
 
the wife used to have a concorde that had a cam sensor act up occasionally, sounds just like yours, hers was intermittent though, not completely shot

someone said good luck with finding on, is this something else that mother mopar screwed us on, different than a regular viper sensor??
